Walter is a playable character in Suikoden Tactics.
Walter introduces the plot and characters of Suikoden Tactics. The game begins with his journey to seek out the adverse effect of the Rune Cannons on humans. He travels with his son Kyril, Seneca, Andarc, and the demi-human Yohn.
Walter is informed that Lord Reinbach II had been installing the rune cannons on various ships. Though he is turned away by Sigurd, he received a tip from Hervey that the infamous pirate Steele had some.
During a night raid of ship, he was shot by a rune cannon at point blank range, transforming him into a horrifying sea monster. No longer able to think for himself, he attacked his son in a frenzy. In the attempt to save Kyril's life, Andarc was forced to slay Kyril's father.
